WAVES A wave is a rhythmic disturbance that TRANSFERS ENERGY.

Waves and Light. A wave is a pattern that moves. A wave is a pattern that moves. As the pattern moves, the medium may “jiggle”, but on average it stays.

The Energy of Waves Light and Sound. The Nature of Waves Wave: a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium.
